Greetings,
On our Cisco 2960-POE switch - connected hosts can see the switch VLAN IP, can get to and from both the corporate network (VPN) and Internet (split-tunnel) - but cannot see each other. We can ping one attached PC and an attached printer from the switch - but the PC can ping the printer.

What is the default-gateway on the connected hosts ?

Thanks for the prompt reply
The deafult-gateway on both devices is the IP address of the local firewall (192.168.3.1).
If we cross-connect the "old" switch (not sure of make/model) to the 2960 - and plug the printer into that switch - the hosts on the 2960 can see the printer.
This is the first time I've ever encountered this loss of intra-switch connectivity.
Thanks.

Hi,
I guess your problem could be caused by
switchport protected
command used on your access ports.
for details.

I guess that's possible - but I haven't seen any ports restricted or shutdown based on any policy violations. They simply will not talk to each other across the switchports.
Am I better off setting the switch back to factory and reconfigure? We are in a VoIP environment on that network - so I've been assigning roles IP Phone + Desktop for those ports where that's applicable. Could that be the problem?
Thanks.

Hi,
as the first step, I'd simply identify the ports to which that PC and printer are connected.
Let's say those are ports FastEthernet0/8 and FastEthernet0/9.
Then I'd simply:
conf t
interface FastEthernet0/8
no switchport protected
interface FastEthernet0/9
no switchport protected
and test if you can Ping between those two devices connected.

A) You can configure data Vlan for Desktops cause i can only see the voice vlan.
B) You default gateway of your Hosts, shoud be your Vlan IP address, which for vlan1 is 192.168.3.253.
sure
